Specification of Letters Patent.

Application filed August 26, 1916. Serial No. 117,061.

To all whom it may concern:

Be it known that l, EUGENE M. STARN, citizen of the United States,

a and a resident of Butte, in the county of Silverbow and State of Montana, have invented, a certain new and useful Improvement in Mountings for Roller-Shades, of which the following is a specification.

My resent invention relates to mountings for r0 er shades of that type now in common use, embodying aroller or elongated cylindrical body, with a stub spindle at one end and a spring in the hollow of the roll at the other end thereof including a catch mecha nism for holding the same in an adjusted position, said catch mechanism including a key, polygonal in cross-sectlon, whlch protrudes at the end of the cylindrical body or roller at its end opposite said stub spindle.

The principal objects of my invention are to provide a mounting of the character described which may be easily disposed into operative relation to the roller shade without alteration of the same, and easily applied to the window casing without destroying the architectural effect of such casing, from an esthetic standpoint, and without marring or in any way defacing the window casing; to provide mountings oi the charac-' ter described which will enable the cylindrical body or roller to be quickly disposed at any height with respect to the window sash afiording' ventilation at the upper portion of the window, if desired, without the shade obstructing free movement of the air therethrough; and, to provide mountings of the character described which may be placed into operative relation to the roller shade and window casing without the use of tools or other accessories, enabling the person to quickly aline the shade with the uprights or ambs of the casing if it is not primarily Other objects of my nvention will appear in the following detailed description, taken in connection with the accompanying drawing, forming a part of this specification, and in which drawings;

Figure 1 is an elevation of theupper portion of a window casing showing a roller shade in vperative relation thereto and supported by mountings embodying my invention.

Fig. 2 is an enlarged detailed view, partly in elevation and artly in longitudinal section through a ro er and mountings therefor, a portion of the roller being broken away and removed to condense the view.

Fi 3 is a view similar to Fig. 2 but showing all of the'parts in elevation.

Fig. 41- is an enlarged sectional view on the line 4t of Fig. 2.

Fig. 5 is an enlarged sectional view on the line 5-5 of Fig. 2. f

Fig. 6 is a perspective view or a bufier and a retaining device extending therefrom.

In the drawings, where similar characters refer to-similar parts throughout the several views, A designates a window casing lncluding jambs B; C a roller shade comprising the shade proper D and roll or elongated cylindrical body E including the usual stub spindle F and key G of catch mechanism H at opposite ends of the body E; J a mountingrfor the end of roll F at the stub spindle and, K a mounting for the end of the roll at key G.

Referring first to the disposition of the roller shade with respect to the casing A, it 1s contemplated. to arrange the roller shade and its mountings so as to be disposed between the jambs B in contra-distinction to arranging the roller shade over the face of the window casing where it is apt to destroy the architectural efi'ect of said casing. It is to be understood, however, that under certain conditions it-might be desirable to provide abutments other than the jambs B and such may be accomplished without departing from the spirit or scope of my invention.

The roller E- may be of any suitable type, such as are now in common use embodying the stub spindle F which is rigid with the lroller and the key G, polygonal in crosssection, which is to be held rigid with the window casing, the main body of theroller being 'revoluble with respect thereto, the catch mechanism H including the usual ratchet member 7 and dogs 8 cooperating therewith, said dogs being pivotally carried by the main body of the roller as by pins 9.

Referring now to the mounting J, it comprises a bearing designated enerally by 10 and receiving the spindle F; a body 11 adapted to engage the jamb of the window casing A or other abutment; and, a device 12, such as an expansion spring, for yield ably forcing said body 11 in a direction away from bearing 10.

The bearing 10 preferably comprises a disk or plate 13 provided with an annular lid ball-race 14; a coacting plate or disk 15 provided with a ball-race 16 confronting the ball-race 14 and, in the example shown, rovided with an annular flange 17 exten ing from its face opposite to the ball-race '16; balls 18 in the races 14 and 16; and, a sleeve 19 joining the plates 13 and 15 but permitting rotation of the plate 13 independently of the plate 15. The sleeve 19 is concentrically arranged with respect to the ballraces and may extend through perforations 20 in the plates, the sleeve 19 receiving the stub spindle F.

As to the body 11, it may comprise a cuplike member 21 telescopically arranged with respect to the flange 17 ofthe plate 15 and a buffer '22, such as a disk of rubber or a composition including rubber atthe end of cup-like member 21 opposite to plates 13 and 15.

The device 12 is accommodated within the shell or member 21 and in y the example shown bears against late 15 and the head of said member 21 aving a tendency to move the body 11 in a direction away from plate 15 or hearing 10. Total separation of the body 11 from said hearing may be prevented by a device 23, in the form of a wire of substantial U-shape,- the head ,23' being embedded in bufier 22, with the arms extending through perforations 24 in body 21, lying laterally of the spring or device 12 and extending through perforation 25 in the plate 15, the ends of the arms being turned over as at'26. The arms of device 25 are preferably arcuated as at 27 so as to be resilient. Therefore, upon compressing the spring 12 ,the arms 27 are arched permitting the buffer 22 to be manuallycmoved toward the bearing 10.

With reference to the mountin K, it is.

) substantially like mounting J wit the exception that the bearing 29 includes plates 30 and 31, the first-mentioned late including a flange 32 which engages t e pins -9 of 7 dogs 8, while the plate 31 is provided with a key-way 33 to receive the key G, a sleeve 34 joining the plates 30 and 31,pa$ing through a perforation 35 in plate 30 but provided with arms or extension 36 which enter perforations 37 at opposite sides of the key-way 33. Thus the plate 30 is free to rotate with respect to plate .31 and move with the main body of the roll E, however, the key G polygonal in cross section, fitting into the keyway 31 is held against rotation with respect to the roller E by the mounting K.

In assembling the mountings into-o erative relation to the roller E, the mounting J is arranged with the stub spindle F received by bearing 10 and with the plate 13 engaging the end portion of the roller E. The

mounting K is arranged so that the key G extends into key-way 33 with the plates 30 engaging the other end portion of the roller in operative relation to the window casing. As the shade proper D is drawn downwardly its margins maybe alined with respect to the uprights of the window casing by moving one or the other of the mountings upwardly or downwardly. It is to be observed that the mountings in no way defaces the window casing since there are no metallic parts engaging 0r driven into the window casing.

Changes in details maybe made without.
